Devices for Generating Mode Commands

4. The device of claim 3, wherein the second section control circuit generates a second bit of the first section signal which is deactivated to terminate the second internal operation when the second bit of the first section control signal is activated for the first time in synchronization with the oscillating signal.

6. The device of claim 5, wherein the section control signal selector outputs the first pre-signal as the first section control signal when the first mode signal is activated, and outputs the second pre-signal as the second section control signal when the second mode signal is activated.

7. The device of claim 1, wherein the mode command generation circuit includes a first mode command generator configured to output the oscillating signal as the first mode command during a section in which the first section signal is activated.

9. The device of claim 7, wherein the mode command generation circuit further includes a second mode command generator configured to output the oscillating signal as the second mode command during a section in which the second section signal is activated.

10. The device of claim 7, wherein the mode command generation circuit further includes a mode end signal generator configured to generate a mode end signal that is activated when one of all of the internal operations included in the first mode operation are terminated and all of the internal operations included in the second mode operation are terminated.

11. The device of claim 1, further comprising an oscillator configured to receive an oscillating control signal which is activated when one of the first mode operation is performed and the second mode operation is performed to generate the oscillating signal.

12. The device of claim 1, further comprising a mode signal generation circuit configured to generate the first mode signal which is activated when the first mode operation is performed, and generate the second mode signal which is activated when the second mode operation is performed.

15. The device of claim 14, wherein the second section control circuit generates the second bit of the section signal which is deactivated to terminate the second internal operation when the second bit of the section control signal is activated for the first time in synchronization with the oscillating signal.

16. The device of claim 13, wherein the mode command generation circuit outputs the oscillating signal as the mode command during a section in which the section signal is activated.
